Temporal Characteristics of High-Frequency Lower-Limb Oscillation during Freezing of Gait in Parkinson’s Disease
Figure 2
(a) Onset of lower limb freeze band activity relative to the back sensor (mean and SEM of both limbs). High frequency (3–8 Hz) oscillation occurred first in the feet, shanks, thighs, and then back, over a period of 250 ms. (b) Peak power (mean and SEM) decreased from the distal to proximal sensors.
